In order to increase fishing efficiencies of the fyke net used in the coast of Cheju Island water tank experiment was caried out entering and escaping behavior using nets that were reduced to 1/20 of the size of fyke net and were improved to have antrance structure, and Mackerel Scomber japonicus as experimental fish. The results of measurement are as follows: 1. Fish school behavior in the main net was showed two different patterns: swimming in a circle in the right space of the main net and swimming back and forth in ellipse in the right and left space. 2. The swimming speed of mackerel school was 24.9. 12.6 and 32.0cm/sec in the center space. right space of main net and in the mouth. 3. The entering rate of fish school was 40% in net with 35cm length of the upper and funnel net in the mouth of fyke model net and 49% in conventional type fyke model net. 4. The escaping rate of fish school was 10% in net with 35cm length of the upper and funnel net in the mouth of fyke model net and 69% in conventional type fyke model net. 5. The remain rate of fish school was 90% in net with 35cm length of the upper and funnel net in the mouth of fyke model net and 31% in conventional type fyke model net.

Objectives : This study evaluated the explanatory styles, dysfunctional attitudes and their relationship to depressive symptoms in patients with major depressive disorder and schizophrenia. Methods : Twenty nine patients with major depressive disorder, 35 patients with schizophrenia and 43 normal controls Completed the self-rating scales for explanatory styles (Forced Attributional Style Questionnaire, FASQ), dysfuncdonal attitudes (Dysfunctional Attitudes Scale, DAS), depressive symptom (Beck Depression Inventory, BDI), and hopelessness (Beck Hopelessness Scale, BHS). Results : Patients with major depressive disorder (BDI : 27.0±14.30, BHS : 8.81±6.59) and those with schizophrenia(BDI : 16.1±2.39, BHS : 5.6±5.21) had significantly higher BDI and BHS scores than normal control (BDI : 5.8±5.53, BHS : 2.4±3.61). DAS total scores were significantly higher in patients with major depressive disorder (171.3±22.96) and schizophrenia (161.8±32.96) than normal control (139.9±30.94), but there were no significant differences between patients with major depressive disorder and schizophrenia. Regarding FASQ subscales, the global positive score was significantly higher in patients with major depressive disorder (3.7±1.36) and with schizophrenia (3.4±1.73) than normal control (2.5±1.39). BDI total scores correlated significantly with stable negative and global negative scores of FASQ in major depressive disorder, but only with global negative scores in schizophrenia and normal control. DAS total scores correlated with BDI scores not only in major depressive disorder, but also in schizophrenia and normal controls. Conclusion : The results suggested that dysfunctional attitude is significantly severe not only in patients with major depressive disorder but also in schizophrenic patients compared to normal control. Also, there seems to be a positive correlation between Cognitive distortion and depressive symptoms not only in major depressive disorder, but also in schizophrenia. However, this study is not able to clarify their causal relationship. Further study is necessary to clarify the causal relationship between depressive symptoms and cognitive distortion and the cultural effect on cognitive distortion in major depressive disorder and schizophrenia.

최석진,남상준,류재명,손용택,이동엽 한국사회과교육연구회 2000 사회과교육 Vol.- No.33

이 연구는 남북한 통일을 대비하여 북한 고등중학교 지리 교육과정 및 교과서를 비교·분석한 것이다. 남북한의 학제와 지리과 영역의 교육과정상의 위치가 다르고 북한의 교육과정을 입수할 수 없었기 때문에, 입수한 북한의 고등중학교 1학년부터 5학년의 지리교과서 5종(1991년도부터 1993년도 발행분)을 대상으로 분석하여, 남한 6차 교육과정의 중학교 사회와 고등학교 공통사회(한국지리) 및 세계지리 내용을 비교 분석하였다. 연구 결과는 다음과 같다. 첫째, 남북한 중등학교 지리교육은 교육과정상의 편제에서 북한은 고등중학교 전학년에 걸쳐서 지리가 독립과목으로 편제되어 있으나, 남한은 중학교 사회과에 통합되어 있고, 고등학교에서는 공통사회에 포함되었으며 세계지리가 선택과목으로 되어있는 등 지리교육 내용계열과 조직체계도 차이가 난다. 둘째, 지리 교육의 이념과 목표에서, 남한은 민주시민 양성을 목표로 하여 개인의 지리교육적 성취가 주된 것이나, 북한은 집단 구성원으로서의 개인 양성에 중점을 두고 있다. 이러한 차이점은 정치체제의 차이에서 비롯된 것이며 지리교육 내용의 구성과 강조점등에서 많은 차이점을 나타내게 하고 있다. 셋째, 지리교육 내용 구성과 서술 등에 차이가 있다. 국토지리와 세계지리 및 계통지리와 지지의 배열과 비중 등이 다르며, 내용의 서술에서도 차이점을 볼 수 있다. 특히, 북한에서는 국토지리와 자연지리의 비중이 높으며, 주요 개념과 용어 설명에서 남한과 다른 점이 보인다. 넷째, 교과서의 구성과 교수-학습 방법 및 자료 사용에서 차이점이 보인다. 북한에서는 실습, 실험 등이 강조되면서 실제적인 기능 향상에 많은 비중을 두고 있으며, 사진에 비해서 그림을 사용하는 삽화의 비중이 높다. 교과서의 외형적 체제와 지질 등에서 차이가 큰데, 이 점은 경제력의 차이에서 비롯된다. 본 연구 결과 남북한은 모두 지리교육을 중등학교에서 중요시하고 있으며, 지리교육을 통하여 소기의 목표 달성에 노력하고 있으나, 서로간에 상당한 차이점도 발견할 수 있었다. The purpose of this study is to understand the similarity and differences of the geography textbook between north and south Korea in preparation for the unification. Five geography textbooks for the first through fifth grade in secondary school were used in the analysis of the geography curriculum for secondary schools in North Korea. The major findings of the study are as follows: First, South Korea takes an integration approach to teach geography as part of the social studies education whereas North Korea treats geography as an independent subject throughout secondary school. Second, South Korea aims at nurturing democratic citizen, emphasizing individual achievement, whereas North Korea puts emphasize nurturing citizenship within community. Third, difference is noted in the organization and content of the geography curriculum between the two Koreas. North Korea puts more emphasis on national geography and natural geography than does South Korea. Forth, North Korean textbook is different from that of South Korea in that the former emphasizes on performance skills through hands-on practice and training. Also North Korean textbook uses more drawings than pictures. Despite differences in various aspects of curriculum and textbooks, there are a great deal of overlap in essential concepts and contents covered in two Koreas' geography textbooks. Both Koreas value geography education in the secondary schools and make efforts to fulfil the educational objectives in geography.

The purpose of this study was to investigate the effect of demineralized dentin matrix on osseointegration of implants. Seven mongrel dogs of either sex, weighing about 15kg, were used. The lower 1st, 2nd, 3rd, and 4th premolars of both sides were extracted under general anesthesia. Implants were inserted 3 months after extraction of the teeth. In the control group, socket wall around the implant was sutured without any graft material. The experimental groups were divided into the two : the DDM group was filled with demineralized dentin matrix into the hole of the implant and the DDCM group filled with demineralized dentin and collagen matrix. The animals were killed 1, 2, 4, 8, and 12th weeks after the implantation. Tissue specimens obtained were processed for light and fluorescent microscopic examination. Results obtained were as follows : 1. At one week after the implantation fibrous connective tissue from the surrounding periosteum was observed at the superior portion of the alveolar bone-implant interface and blood clot was formed within the hole of the implant in control group. Endosteal proliferation from the cut surface of the compact bone was observed in the both experimental groups. 2. At two weeks after the implantation the interspace between the alveolar bone and implant became narrow, and endosteal proliferation and woven bone formation from the cut compact bone were noted in control group. Newly formed trabecular bone was blended with demineralized dentin matrix in the both experimental groups. 3. At four weeks after the implantation some fibrous tissues were still observed in the interspace between the alveolar bone and implant in control group. However, with osteoinduction and osteoconduction by deminealized dentin matrix, osseointegration without intervening of fibrous tissue was observed in the both experimental groups. 4. At eight and twelve weeks after the implantation a complete osseointegration was noted and demineralized dentin matrix was almost resorbed in all groups. 5. By fluorescent microscopic examination, bone formation and osseointegration were noted earlier in the experimental groups than in the control group. 6. Bone healing of the DDCM group was similar to that of the DDM group. These results suggest that demineralized dentin matrix can be used as a useful material for early fixation of implants by promoting new bone formation and osseointegration of implants.

공간 데이터에 대한 최근접 질의 처리에 관한 연구

이석균,류승환 단국대학교 1999 論文集 Vol.34 No.-

In spatial database systems, various kinds of queries exist. A frequent type of queries in spatial database systems is the query to find nearest neighbors. Many studies have been performed on processing such queries, and one representative work, which uses index structure of R-tree family, is 「Nearest Neighbor Queries」 by Roussopoulos. However, the algorithm proposed by Roussopoulos has suffered perfomance decrease during searching, since his algorithm does not utilize all the information on the nodes already visited. In this paper, in order to resolve this problem, we present an improved algorithm to find nearest neighbors using a global priority queue. Finally, by experimenting these algorithms on various test data, we show that the performance of our improved algorithm is superior to the Roussopoulos's algorithm.

Necrotizing fasciitis (NF) is a rare, life-threatening infection resulting in necrosis of the skin, subcutaneous tissue, and fascia. A very severe and usually fatal fasciitis is caused by a virulent species of streptococcus that is often referred to as the "flesh-eating bacteria". Mortality rates have been noted high. Certain conditions can predispose patients to NF, such as diabetes mellitus, immunosuppressive medications, and AIDS. Patients usually complain of excessive pain as well as constitutional symptoms. Because of this rapid progression, it is important to diagnose and treat NF quickly to decrease mortality. Treatment includes broad-spectrum antibiotic coverage, nutritional supplements, hemodynamic support, wound care, and prompt surgical debridement. We report a case of a 51-year-old man who had presented with right hip pain. Previously, he had been diagnosed with diabetes mellitus and alcoholic liver cirrhosis.
